Introduction From 2016 to 2021 after 5 iterations of upgrades and revisions the fifth generation EM20 EM40 brushless ESCs with high appearance and top performance are now here The 20x20mm installation hole distance is still a good choice for small wheelbase aircraft The 40A current increase brought by this upgrade can be set to be suitable for use on 5 inch aircraft The changes brought about by this upgrade first of all the size of the model is more suitable 29mm in length and 27mm in width not too long the size is suitable even at the level of 40A this size is small The second is the change of the pad The large pad of the power supply part reserves the space for the line thickness which makes the soldering more accommodating At the same time the contact area between the wire and the pad is larger which makes it easier to solder and it can also be more soldered Which makes the soldering firmer and eliminates false soldering large through holes are also reserved for the pads of the motor part with more tin on both sides and larger areas and the wires are firmer and will not be soldered or torn off the pads In addition the current meter is also integrated into this 20x20mm ESC and it is output to the flight controller through a flat cable Therefore the socket is changed from the original 6p to 8p Description Item Name EM20A 40A Four in one ESCInput voltage 2 6S LiPoContinue current 20A 4 40A 4BEC NoAmmeter YesInstallation Hole pitch 20
